[llvm] r229841 - Reverting r229831 due to multiple ARM/PPC/MIPS build-bot failures.

[Daniel Sanders]

It defaults to empty for me.

For the Mips failure, it seems to be spending a very long time processing the 'extern const MCInstrDesc X86Insts[] = ...' declaration. If I delete it or reduce it to a single entry, the file compiles quickly.
